TRANSOM-FIXTU RE.

SPECIFICATION forming part of Letters Patent No. 239,338, dated March 29, 1881.

Application filed September 20, 1879.

To all whom it may concern Be it known that I, FRANCIS V. PHILLIPs, of Chicago, Cook county, and State of Illinois, have invented certain new and useful Improvements in Transom-Fixtures, of which the following is a specification.

This fixture is intended to be used upon those transomswhich are swung upon central pivots; and my object in devising the same,

has been to combine with a pivot for such transoms a lock, whereby the transom may be secured in any desired position.

The nature of the invention willbe fully understood from the accompanying drawings, forming a part of this specification, and the following description.

In said drawings, Figure 1 shows a transom to which my combined center and lock have been applied. Fig. 2 is a front perspective, and Fig. 3 a back perspective, of the center and lock detached. Fig. 4 shows the device with the lock thrown out of the engagement.

Fig. 5 shows the locking-catch detached.

In said draWings,A represents aplate, which is secured to the outside of the transom. EX tending back from this is an arm, A, bearing the center B, upon which the transom swings, a bearing being furnished by the'sooket-piece C, which is let into the side door-jamb. The center B is slotted upon one side, and in such slot is placed a spring-catch, D, which is operated by a pull, D, passing through the plate A to the front of the transom, and there provided with a knob, D the spring at forcing it away from the pull-handle at all times. The bearing in the socket-pieceis provided with several slots, 0, distributed around the opening and adapted to receive the catch D.

When it is desired to open the transom or change its position, the handle or knob D is pulled until the latch is retracted entirely within the slot in the center C. The transom can then be swung into any position, and is then looked in such position automatically by the spring-catch entering that one of the slots 5 in the bearin g-piece coincidin g with its chan ged location.

The handle or knob D has an inward projection, d which sets in between the stops at upon the outer face of the plate A.

When it is desired to detain the latch from engagement with the slots in the bearing-piece, the handle D after being pulled out, is turned upon the pull-rod D, so that it occupies the position shown in Fig. 4, with its projection d resting against the stops at a. This leaves the transom free to be swung, and obviates the holding of the latch by the operator.

The apparatus can be used at either end of the transom without change of construction, and it is very simple, inexpensive, and durable.

Instead of providing the bearing with a series of slots to receive the catch and attaching the catch to the center, the catch may be placed in the door-jamb and the center itself be provided with a series of slots to receive it.

Both the pivot and locking devices are located within the limits of the transom and out of sight. Thus the appearance of the transom is but slightly changed. Also, by my construction, the wood need be cut away but very little more than in inserting the old style of centers.

1 claim- 1. The combination, with a centrally-swung transom, of a pivot and bearing set back of the front, a catch located at the pivot and acting to lock the transom from turning, and a pull extending to the front of the transom for releasing the catch, substantially as specified.

2. The combination, with a transom-center and a slotted bearing for such center, of a spring-catch and a pull for operating the same, substantially as specified.
